What Is a Trial Balance? How to Prepare and Use One
A trial balance lists all ledger account balances to verify that total debits equal total credits. This guide explains what a trial balance is, how to prepare one, and what it does and does not tell you.
What Is a Trial Balance?
A trial balance is a list of all ledger account balances at a given point in time, showing the debit or credit balance of each account. Its primary purpose is to check that total debits equal total credits — confirming that the double entry bookkeeping has been applied consistently. If the two columns do not agree, an error has occurred somewhere in the accounting records.
How to Prepare a Trial Balance
List every account from the general ledger. For each account, enter either the debit balance or credit balance in the appropriate column. Asset accounts and expense accounts typically have debit balances. Liability, equity, and revenue accounts typically have credit balances. Sum both columns. If they are equal, the trial balance agrees.
What a Trial Balance Does and Does Not Tell You
A trial balance confirms that debits equal credits — but it does not guarantee the accounts are correct. It will not detect: an error where a transaction was posted to the wrong account (but the correct side); a transaction that was omitted entirely; or compensating errors where two mistakes cancel each other out. These are the errors that do not affect trial balance agreement.
Types of Errors
Errors of omission: A transaction was not recorded at all. Errors of commission: A transaction was posted to the wrong account (but correct type). Errors of principle: A transaction was posted to the wrong type of account (e.g., capital expenditure expensed). Compensating errors: Two errors that cancel each other out. Transposition errors: Digits reversed — these often show as a difference divisible by 9.
From Trial Balance to Financial Statements
The trial balance is the starting point for preparing financial statements. Revenue and expense account balances feed into the income statement. Asset, liability, and equity balances feed into the balance sheet. This is a core process in ACCA FA and CIMA F1, and understanding it thoroughly accelerates progress through all subsequent accounting papers.
